2019-04-09bpf, selftest: test {rd, wr}only flags and direct value accessDaniel Borkmann1-0/+159
Extend test_verifier with various test cases around the two kernel extensions, that is, {rd,wr}only map support as well as direct map value access. All passing, one skipped due to xskmap not present on test machine: # ./test_verifier [...] #948/p XDP pkt read, pkt_meta' <= pkt_data, bad access 1 OK #949/p XDP pkt read, pkt_meta' <= pkt_data, bad access 2 OK #950/p XDP pkt read, pkt_data <= pkt_meta', good access OK #951/p XDP pkt read, pkt_data <= pkt_meta', bad access 1 OK #952/p XDP pkt read, pkt_data <= pkt_meta', bad access 2 OK Summary: 1410 PASSED, 1 SKIPPED, 0 FAILED Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2019-01-27selftests: bpf: break up test_verifierJakub Kicinski1-0/+219
Break up the first 10 kLoC of test verifier test cases out into smaller files. Looks like git line counting gets a little flismy above 16 bit integers, so we need two commits to break up test_verifier.
